The pursuit of SDGs 7 (Affordable and Clean Energy) and 12 (Responsible Consumption and Production) has spurred innovative renewable energy solutions. Indonesia, with its significant renewable energy potential of 417.8 GW—14% of which comes from water resources—presents an excellent opportunity for pico-hydro turbines to provide electricity in remote areas. This research focuses on improving the performance of the Turgo turbine, a type of pico-hydro turbine with a capacity of less than 5 kW, by using degradable materials. Specifically, coconut shells are explored as an alternative material for turbine blades, given their strength, durability, and cost-effectiveness. This study conducts a thorough analysis of blade geometry, depth ratio, and angle variation to optimize turbine efficiency. Analytical methods are used to design the turbine and assess the impact of different angles on its efficiency. These designs are then validated through numerical simulations and experimental tests. The optimal depth and radius of curvature ratio (T/w) of 0.275 was found to yield the highest hydraulic efficiency. The results showed that the turbine with coconut shell blades achieved a simulation efficiency of 49%, an experimental efficiency of 44%, and an electrical efficiency of 33%. These findings demonstrate the practicality and effectiveness of using degradable materials like coconut shells in renewable energy applications. This research highlights the potential of coconut shell-based Turgo turbines to deliver sustainable and affordable energy solutions, particularly in remote Indonesian communities where access to electricity is limited.By incorporating degradable materials into turbine design, this study supports environmental sustainability and advances renewable energy technologies. The findings align with global efforts to promote responsible consumption and production, contributing to a more sustainable energy future.
